Abstract (en)

[origin: EP1670121A1] The machine has stator and rotor arrangements (34, 32) arranged coaxially with respect to one another. The rotor arrangement has permanent magnets that are embedded in a rotor body. A magnetic sensor (52) measures a rotational position of the rotor body, where the sensor is located directly opposite to an end face. A sleeve protrudes in an axial direction beyond the end face of the rotor arrangement.
